To al?, whom t mag/ concorm Be it known that I, CHARLES F. Borna, a citizen of the United States, and a residentofT Hopedale, county of Worcester, State of Massachusetts, have invented an Improvement in Take-Up Control for Looms, of which the following description, in connection with the accompanying drawings, is a specification, like characters on the drawings representing like parts.

This invention has for its object the production of means for so controlling the takeup mechanism of a loom that take-np will be arrested under certain conditions, particularly when the protector mechanism operates.

In looms provided with fantibang mechanism the crank-shaft may turn overa number of times after the protector mechanism operates Without causing anydamage as the Warps are slackened, so that the shuttle cannot break them even if it stops in the shed. As the shuttle is not picked during such movement of the loom, the take-up should not act. Now if the shuttle stops Within the shed, but not in front of the lling fork or detector; the absence of filling is detected bythe fork, and such detecting action arrests or prevents takeup. On the other handfif` the shuttle stops in front of the fork it Will tilt the latter, and thereby prevent the arrest oftake-up by the :filling-detecting means.

My present invention "obviates this difficulty by providing for the arrest of take-u p by or through the operation of the protector mechanism, and this is effected in a very sim-" ple and efficient manner. So long as thereis no shuttle fault the take-up mechanismwill be controlled by the filling-detecting means, as is the case in my United States VPatent No. 716,282, dated December 16, 1902; but upon the occurrence of a shuttle fault -the `protector assumes joint control ofthe take-up.

The various novel features of myinventio will be described in thesubjoined specification and particularlypointed outin the following claims.

Fig. 5 is a sectional view on the line 5 6, Fig. 2, looking toward the left, showing the manner in which takeup is arrested'by or through the filling-detecting means. Fig. 6 is a similar View, but showing the arrest of take-up by or through the action of the protector mechanism; and Fig. 7 is an enlarged detail of a portion of the mechanism shown Ain Figs. 5 and G, by which the take-up is arrested.

The breast-beam 2, lay 3, lay-sword 4, the controlling or operating rock-shaft 6, having .anupturned arm 7 in the path of the slidefa of the filling fork or detector fx, Fig. l, of any usual construction, the take-up roll 11, its shaft 12, having an attached Worm-gear 15 in mesh with `a Worm 16, fast on a shaft 17, .the bracket 14, in which said shaft is rotata bly mounted, and the ratchet 21, fast on the shaft and having circularly-arranged teeth .22 on its inner face, maybe and are all as in my Patent No.` 716,282.

The actuating-pand 27, pivotally mounted on shaft 17 and provided with an elongated opening 28, (see Fig. 4,) its tooth or lug 29 to cooperate With the ratchet, the projections 30 to bear on the inner face of the ratchet, the

guide -arm 3l, and the depending finger 32 .are also substantially as in said patent, the

arm 3l being connected bya link 35 with the arm 37, attached to the laysword, the vibra- 'tions of the lay operating the pawl.

.tends in front of the paWl-finger 32, so that when the rock-shaftis turned by orthrough an abnormal condition of the iilling, such as failure or breakage or its substantial exhaustion in the shuttle, said arm 41 acts to tip the pawl and prevent the engagement of the pawl-lug 29 with the ratchet-teeth, thereby arresting the take-up.

In my present invention the rock-shaft 6 is also provided with a downturned arm, as 41; butit does not engage the pawl, though it is arranged to arrest take-up upon the occurrence'of an abnormal condition of the filling. Herein the free end of -the arm 41 has pivotally connected with it a longitudinallymovable bar 42, extended toward the back of the loom, and at its rear end said bar is reduced in size, as at 43, to rest upon the upper edge 52 of an ear 5l, extended laterally from a bracket 50, secured to the loom side. Adjacent the part 43 of the bar the latter is provided with upper and lower cam-faces 44 and 45, (see Fig. 7,) oppositely inclined or beveled, the lower face 45 being adapted to engage and ride up on the face 53 of the ear 51 when the bar is moved rearwardly in the direction of arrow 100. rlhe bracket has fulcrumed upon it at 54 a rocking or tilting member 61 62, the part 61 being upturned fora purpose to be described, while the depending part 62 is segmental in shape and is provided with an inclined lateral shelf` 63 in the path ofthe cam-face 44. A link 46 is pivotally connected at 47 with the back of the pawl-iin'ger 32, and the other end of the link is pivotally connected at 4S with the segmental part 62 of the rocking or tilting member. The normal position of the parts is shown in Figs. 1 and? when the loom is working properly. If the rock-shaft 6 is turned by the outward swing of arm 7, however, the dependingarn1v4l is swung backward, moving the bar 42 in the direction of arrow 100, Fig. 7, and the cam-face 45 rides up on the face 53 of the ear 51, lifting the rear end of the bar. 4The cam-face 44 also engages the shelf 63, and as said cam-face is moved rearwardly and also upward the engagement with the shelf operates to turn the member 61 62 on its fulcrum in the direction of arrow 99, Fig. 7, and through the link 46 the pawl is tipped into the position shown in Fig. 5, disengaging the pawl-lug 29 from the ratchetteeth and arresting take-up. When the rockshaft 6 returns to its normal position, the bar 42 is withdrawn to its normal position, the part 43 thereof dropping down upon the ear 5l, and the pawl is moved into cooperative engagement with the ratchet by the spring 33.

In order to provide for control of the take-up at times by the protector mechanism, I have provided means whereby the member 6l 62 will be rocked or tilted upon the operation of the protector mechanism. Alive frogc is mounted on the loom side to be engaged and moved by the dagger d3 of the protector mechanism, Fig. l, upon improper boxing of the shuttle, said frog acting, through a knock-od lever c2 c3, Fig. 2, to release the shipper L. The whip-roll W, Fig. 1, is mounted in arms m', fulcrumed at m, and maintained locked in position under normal circumstances by means forming no part of this invention, one member of such means being shown at n2, however. The locking means is controlled by means of a link nu, connecting the frog with an uptu rned arm '11.10, fast on a rock-shaft N, to which the member n2 is secured, substantially as in au application, Serial lNo. 134,234, filed by me January 9, 1903. When the frog is engaged and moved forward by the dagger upon improper boxing of the shuttle, the link w12 is moved by the frog to swing the arm ll'tm'forward, unlocking the Whip-roll and causing the same to move to slacken the warps, the same forward movement of the frog releasing the shipper. This is an antibang mechanism, l[he loom being free to turn over one or more times after shipper release, the positive slackening of the warps preventing any breakage of the same if the shuttle stops in the shed. The upturned part 61 of the rocking or tilting member 61 62 is located in front ofthe frog, and when the latter is moved forward, as described, it engages the part 61 and depresses it, as shown in Fig. 6, swinging the member on its fulcrum 54 in the direction of thearrow 99, Fig. 7. Thereby the link 46 is moved longitudinally to tilt the pawl on the shaft 17, disengaging the lug 29 from the ratchet-teeth and arresting take-up by or through the operation of the protector mechanism. It will be manifest, therefore, that the rocking or tilting member 61 62 and its connection with the pawl will be operated to arrest take-up by or through some abnormal condition of the lling or by or through the operation of the protector mechanism.

The stoppage of the shuttle in the shed in front of the iilling-forkand acting to tilt the latter, as has been before referred to, would manifestly prevent arrest of lake-up at such time were the control of the take-up Wholly dependent upon the filling-fork.

By causing the operation of the protector mechanism to arrest take-up, however, the failure of the fork to secure the desired effect is corrected and arrest of take-up insured at the proper time.

My invention is not restricted to the precise construction and arrangement herein shown and described, as the same may be varied or changed in diiferent particulars without departing from the spirit and scope of my invention, only one practical embodiment thereof being referred to herein.
